Episode 103: Corals of the Deep

Episode Description:

In the deep waters off Florida’s Atlantic coast grow magnificent structures, capable of reaching 300 feet in height. These are the corals of the deep sea. Porcelain-white and centuries old, few humans have seen these delicate reefs. The Ivory Tree Coral, Oculina varicosa, and Lophelia pertusa flourish in harsh, sunless environments, yet these branch-like formations provide food and shelter for a variety of deepwater organisms. Rich in biodiversity, this mysterious underwater kingdom is threatened by destructive fishing practices such as bottom trawling. However, a recently proposed 23,000 square mile marine protected area could save these fragile reefs from ruin.

Changing Seas follows scientists 50 miles offshore on a unique expedition to further pinpoint the locations of these thousand-year-old coral mounds. Using cutting-edge technology, experts from three of the country’s premier ocean research institutions have joined forces to investigate portions of Florida’s seafloor. The science team lives aboard a research vessel for seven days. Their mission: To scan the ocean bottom and create detailed maps using specially built Autonomous Underwater Vehicles or AUVs. Their results could help save Florida’s corals of the deep. But what will they find?

Catalyst One Expedition Log

For each day of the CATALYST ONE mission, scientists, engineers, and other experts share their experiences online as they investigate the ocean floor with newly built Autonomous Underwater Vehicles or AUVs.

Harbor Branch Embarks on First Phase of Ocean Exploration Partnership

“On Dec 4 at mid day, Harbor Branch Oceanographic Institute's research vessel Seward Johnson sailed into the Straits of Florida for an unprecedented up-close look at the deep coral reefs that exist off Florida's central east coast. Harbor Branch at FAU senior research professor John Reed will spend the next six days mapping the deep Lophelia reefs that until now have remained hidden 50-100 miles off the coast of central Florida.”

Harbor Branch Oceanographic Institute

As a research institute at Florida Atlantic University, Harbor Branch Oceanographic Institute work involves “ocean technology, coastal and deep sea exploration and research, marine biotechnology, aquaculture, ocean and human health, and marine science education.”

Oceana/Deep Sea Corals

Learn more about the deep sea corals that grow near Florida and other coastal states. Explore online the mysterious deepwater ecosystems of the Southeastern United States and discover how Oceana, “the largest international organization focused on ocean conservation,” is working to help protects these important natural resources.

Waitt Institute for Discovery CATALYST Program

“The Waitt Institute for Discovery’s CATALYST Program is a series of deep-sea expeditions that will significantly transform undersea exploration and the future of our oceans. The program makes available for the first time a versatile and highly portable deep-sea tool kit and operations team that is rapidly deployable all over the world.”

Waitt Institute for Discovery

“The Waitt Institute for Discovery is a non-profit research organization that serves as an exploration catalyst, enabling scientific pioneers to transform the ways in which discoveries are made. The Waitt Institute for Discovery implements innovative technologies in the field through collaborations with world-renowned scientific institutions, synthesizing global expertise and accelerating groundbreaking research.”

What is REMUS?

Remote Environmental Monitoring Units -“These low-cost autonomous underwater vehicles are designed by OSL personnel to operate simply with a laptop computer. At less than 80 lbs, the lightweight design facilitates launch and recovery operations. REMUS can also carry a video plankton recorder, a plankton pump, video cameras, pop-up cameras, an electronic still camera, and most recently, a towed acoustic array, making it a versatile tool for any mission.”

Woods Hole Oceanographic Institution/Remus Group

“WHOI is the world's largest private, nonprofit ocean research, engineering and education organization. REMUS is an acronym for Remote Environmental Monitoring Units. These vehicles are robotic submarines resembling torpedoes that navigate without a human crew onboard and without cables connecting them to research vessels at the sea surface.”
